switch is in closed position and the de-. position, is disposed'in' path of the trolleyavheel, so as toy be'engaged thereby. Said detent is theretent in looking the forelifted into the position shown in full lines inFig. 1, leaving the switch29 free I to 'be'returned to normal open circuit po- "sition shown in full lines under the action of its own weightand that of the spring 40. What I claim is;

Lln a device for connecting and disconnecting' adjacent sections of a sectional trolley wire or similar conductor, the combination with a normally open switchadapted to be closed by acar passing in one direction, of means for locking said switch closed, said means being operableby a ca-i' passing in theopposite direction to permit the switch to resumeits normally open positioiri,

2. In a device for connecting and disconnecting adjacent sections of a sectional trolley wire, or similar conductor, thejcombina- 'tion. with a normally open switch depending from'one of said sectionsand adapted to be closed by ,a car passing in one direction, of means automatically released by the closing of said 's'witch for locking said switch, said 'lockingjmeans beingxprovided with a part depending in the path of and-operable by the car returning inthe opposite direction whereby the locking neans is made inoperi e a the switchpermitted to return to open position.

3. In a device for'connecting and disconnecting adjacent sections of a sectional trolley .wire, the combination with aterminal; member inelectric connection. with one section,of a switch pivoted thereon at one end I to normally depend in open position in the path of a'trolley moving in one direction, of

axdetent for locking said switch in closed position, said detent' beinginade operative when the switch is closed 'and provided with aitrigger disposed to be engaged by the troley moving in the opposite direction to.re-- lease'the switcln I I t 1 l. In a device for connecting and disconnecting adjacent sections ofa sectional trolley, the combination with aterminal for one section, of switch pivotedthereon to nor-i mally depend in thepath of a trolley moving one direction, a detent forsafid switch eccentricall'y pivoted to said terminal L to j'drop into locking position underits own weight when the switch is c1oscd," said detent being; provided with 'ajtrig ger in the means for locking the switch in closed position, a terminal connected to an adjacent section of the trolley line, carried by the last mentioned terminal for sections, of a switch pivoted thereon at one end to normally depend 1 under its own weight in open position in the path of a trolley moving in one direction,

spring contacts cohperating with the free end of'saidswitch,

and means for forcing said switch position when it is released. a j 6. Ina device ofthe nature described, the combination with adjacent endsof two insulated sections of a trolley line, of a 'non-conductingblock disposed therebetween, .jter

said sections carried Toy-said a switch pivotally and e1ect ric'a-llyv minals for block, connectedwith one of said terminals, a pair of contacts electrically connected to fthe j'other terminal and adapted to cotipe'rate into open with-said switchfa detent mounted on the first terminal for holding the switch lI l fBH- gagement with saidcontacts,1said detent be ing operable apassing trolley to release the switch, and resilient means for throwwhen theswitch is released;

7. Ina device, ofthe character described,

the combination with two adjacent sections of a sectional trolley system, or a terminal;

mg sald switch awayfrom said contacts member connected with eachofsaid sections 3 and means insulating 'saidtehninal members from each other, said niembers being 1 provided with sockets for the, reception of the ends of-said sections, said-; sockets being enlarged inwardly, a wedge fitting the en-.

'l'arged'portion' of each socket, and engaging the end of each trolley section, and a switch pivotally mounted on one of said terminal members and in electric connection-with one of said sections, said switch being operable by a passing car to fclose'thegapg between said sections.

8. In a device of the characterdescribed, contiguous ends of two conductors, of a termi-nal' secured' to the combination with the each conductor, said terminal being provldedwith an enlarged extrem ty, and a pair 'of non-conduct1ngmembers provided "with"recesses-adapting them to'fit around gage theenlarged portions thereof.

the extremities of said terminals and to cm- 9. Inf-a device of'thecharacter described,

the combination with the contiguousends of two conductors, of a terminal securedto vided with a" "-tong'uejhaving an, enlarged "outer; pair of'blocks of non-conduct fing in teri'alfand provided with recesses adapting "them? 't'oi fi't closely about the each conductor, said terminal, being protongues of said terminals, and means forsecuring said blocks together tov clamp said tongues tlierebetween.

10." In a device of the character described, the combination with the contiguous ends "of two conductors,'of a terminal secured ,to .each conductor, said terminalbeing provided with a tongue having an enlarged ,outer end, apair ofjblocks of non-conducting material and provided with recesses adapting them to fit closely about v 'the' tongues of said terminals,iand a; plurality of bolts for securing said blocks togetherto clamp said-tongues therebetween, said terminals being' provided with integral transverse plates coveringth e ends of said blocks.

*lL-In a device of the character described,

for suspendingsaid blocks, connected to one of said bolts. v

12. In a circuit breaker, a plate of insulation,trolley wire holders carried by the ends thereof, a'knifeZswitch for establishing an electrical connection between said holders, and a shoe carried Qby the blade of said switch to bridge the gap between said holders. i 13. In a circuit breaker, a plate of insulae tion, trolleywire holders carried by the ends thereof and providing a gap centrally ofthe' lower edge of said plate, a switch blade-pivotallyconnected tov one of said holders, contact arms carried by the other'holder to receive said blade and establish an electric.

connection between said'holders,,and a shoe carried by said blade and adapted to bridge the gap between said holders.

" let. In a circuit breaker, trolley wire holders providing a gap, asvlliife switch adaptedto provide an, electrical connection between said holders, and a shoe carriedby the blade 01 said switch to bridge the gap between said holders.

15. In' a device of the class described,

trolley wire holders provided with a gap, a

pivoted switch adapted toprovide an electrical connection between said holders, and

a bridging shoe carried by the blade of said switch to bridge. the gapbetween said holders. i p

' 1 16. In a'device .of-the class described, the combination of two terminal members to which theends of the [trolley wires are adapted to be attached, insulating means spacing said terminal members apart to provide a gap therebetween, a switch member for electrically connecting said terminal members, 'andjmeans carried by said switchv 'member for mechanically bridging said gap,

said means being substantially flush with "said terminal members to a permit the trolley to pass said gap. a c

.17. The combination of a pair of terminal -members to which the ends 10f the trolley wire are adapted to be attached, said members havingunder run surfaces formingsubstantially a cont nuation of the trolley Wire, fin'sulatlng means spaclng said termlnal members'apart to forman opengap between said members, a switch member for electrically connecting said terminal members, and means adapted to be positioned in the gap whensaidswitch is operated to provide a mechanical bridge in the gap over which the trolley may run.

I 18. The combination of two members insulated from each and spaced apart to form an open gap,-a movable member adapted to be moved intosaid gap to provide a surface along which the trolley member may run from one member to the other without interruption, and means operable when said member-is moved into said gap for electrically connecting said terminal members.

In testimony whereof I have signed my name to this specification.
